PEGGING-J'ACK.

Specification of Letters Patent No. 22,340, dated December 21, 1858.

Ib all whom t may concern:

Be it known that I, TrioMas D. Barner, of Lowell, in the county ofMiddlesex and Commonwealth of Massachusetts, have invented certain newand useful Improvements in Fegging-Jacks; and T do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, forming a part of thisspecification, and to the letters of reference marked thereon.

The nature of my invention consists, firstly, in providing means ofjacking the last by simply turning the plate or turn- Secondly inproviding means by which the sole of the shoe may be turned from ahorizontal position, either way, until it is brought to a perpendicularposition, or fastened at any intermediate angle, as may be desired, forthe convenience of the o erator. Thirdly, in connection with both t ieforegoing, having it so arranged that the plate or turntable to whichthe shoe is fastened, may be turned freely about, so that either side,or heel or toe may be presented to the operator.

To enable others skilled in the art to make and use my invention, T willproceed to describe its construction and operation.

Figure l, is a plan or top view of my pegging jack. Fig. Q, is a sideelevation of the same. Fig. 3, is a vertical section, taken lengthwiseof the last. Fig. 4, is a vertical section taken crosswise of the last,and show ing how the .shoe may be inclined from a horizontal position.Figs. 5 and. 6 are details, represented separate from the machine forthe sake of clearness. Figs. 4 and 6 are drawn at one half the scale ofthe other drawings. Similar letters of reference in each of the severalfigures represent like parts.

A, Figs. 2, 3 and et, represent the block or post forming a part of theworkmans bench, and to the top of which, the lowest plate `B (or hingeseat) B is securely fastened. A hole is made in the top of the block Afor a short distance down, to allow the link C to play therein.

D is the heel seat for the last and E the toe seat. The toe seat may beplaced in either of the grooves c c c c c to accommodate lasts ofdifferent lengths. The heel seat D has a pin, el, projecting from thetop of it, for which a hole in the last is made to receive it. The heelseat D is one end of a lever, the other end of which, in case a shoelast is to be acked engages direct-ly with the screw F, but when a bootlast is to be jacked, it is necessary to raise the seat D to allow roomfor the leg of the boot between it (D) and the plate T below. This isdone by making the supports Gr, G, taller and introducing another leverH, united with the heel seat lever by means of segments of teeth, asshown in Fig. 3.

The screw F operates t-he lever H and is so arranged that it may beconnected alternately to coupling plate T or to turntable T according asit is required to jack the shoe or to turn itaround freely after it hasbeen jacked. The apparatus to accomplish this, is described as follows:Fastened in the center of the coupling plate, I, is the'upright pin Jwhich forms the axis about which the screw F and turntable T revolve.One end of the screw F projects through the turntable T, and to it, isfastened the short cylinder K, having on its lower edge an annular rimK', Figs. 3 and 4.

L is a grooved and toothed wheel slipping easily up and down on cylinderK. Cast upon one side of this wheel, is the coupling pin L whichprojects downward through a hole or slot in rim Kwthus connecting K andL together so that one cannot turn upon its axis without the other.Fitting in the groove of wheel L, is a yoke M, Figs. t and 5, having aperpendicular rod M projecting from the middle of it, up through theturntable, and supported in bearings in a stand N.

O, is a thumb piece connected to rod M', and by means of which the rodis raised. To hold the rod up after it is raised, the spring latch Q isprovided.

Now the operation of jacking the shoe is as follows: First place thelast in position aforedescribed, then press with the thumb on the springlatch Q so as to liberate the rod M, when it will be forced by thespring P downward so as to carry the coupling pin L into one of theholes, T', in the coupling plate I. This fastens the screw F sta tionaryto the coupling plate I. Now turn the turntable about until the end ofthe lever H has ascended far enough in the groove of the screw F, tobind the toe of the shoe down securely in its seat; this done, raise therod M, by means of the thumb piece O, and the coupling pin L, isdisengaged from the coupling plate I, leaving both screw and turntablefree to turn about their common axis. In order that the screw may beprevented from turning around, a pin R, `Fig. 3, projects downward fromthe turn-table T, which, when the rod M is raised, is'received inbetween the teeth of the wheel M. This prevents wheel M, from turning,and consequently the screw F, also.

Another feature in my invention remains to be described. The convenienceof the workman requires that the sole of the shoe, may be inclined froma horizontal position, and held there, while being operated upon; this Iaccomplish by providing on each side of the coupling plate I a hingejoint S S', either of which may be fastened to the hinge seat plate B byits respective cam lever U or U', in manner seen in Figs. l, 2 and 4L,and thus enable the workman to incline the plate either one way or theother, as may be desired. To fasten the plate in this inclined position,a link C, is provided, one end of which is `jointed to the couplingplate I and a slot running t-he whole length of it, receives the handset screw W. This screw passes to the outside of the hinge seat plate B,and is there provided with a handle X; and as it is turned around, itbrings the nut Y up against the link; which it binds firmly to the hingeseat plate B.

Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent is:

l. I claim the method of jacking the last by turning the plateto whichthe last is fastened.

2. I claim the combination of the lever II screw F and turntable T forjacking the last, substantially as described.

3. I claim fastening the screw F or its equivalent stationary, by meansof the coupling pin I and plate I, so that when the turn table T isrevolved, it shall operate the lever and jack the last, substantially asdescribed.

4. I claim fastening the screw F or its equivalent to the turntable T,after the last has been jacked, by means of the coupling wheel L and pinB, operated by the thumb latch O and spring P, for the purpose ofpreventing the screw F from turning around and loosening the lever I-I,substantially as described.

5. I claim the combination of the two hinges S S cam levers U U hingeseat B the link C and hand set screw W, for the purpose andsubstantially as described.

In witness whereof I have hereunto set my signature this thirteenth dayof November A. D. 1858.
